This is a guide to building up a bike from parts. It should help you get the parts and tools you need to get you pedalling along in no time. It assumes that you have tinkered with your bike, but are not an expert. Hope it helps!
Step 1: Parts
Here is a list of parts you'll need:
Front derailleur (optional)
2 x derailleur cables
2 x brake brakes
4' derailleur housing
4' brake housing
brake hangers front / rear if you use cantilever brakes
I got most of this from Redstone Cyclery http://www.redstonecyclery.com
Step 2: Tools
nuts/bolts (or headset press)
bottom bracket tool
Step 3: Seat post.
Insert the seat clamp, then the post. Grease the heck out of the part of the post that will be in the frame to keep it from rusting together. Then put the seat on.
I then clamp it in the bike stand using the post, but thats up to you...
Step 4: Install headset
Install the headset first. I install the cups using a large bolt, some washers and a nut. The presses it in to place. There is also another instructable I put on here that details the exact process for this step if you are not familiar. http://www.instructables.com/id/EMSFSKUD4QEP286CI1/
Grease the cups up, then press the race on. I bang it on with a adjustable wrench.
Step 5: Fork
Ok put the headset together, grease the bearings, put your stem and any spacers you are going to use on the fork and make a mark with a marker. This is where you are going to cut the steerere tube. NOTE If you have a threaded stem, then just try not to cut it, make it easier, just use some spacers.
Step 6: Cut it loose
So now you take that fork out and cut it about 3mm below the mark you just made.
I used a steerer tube cutting guide, but you can use a zip tie to mark the spot and cut it with a hack saw. Remeber measure twice cut once, cause you can't stretch a steerer tube.
